Abstract:
A kiln plant for manufacturing cement, said plant comprising a kiln (1), a cooler (4), a calciner (2) with subsequent separation cyclone (9), a burning compartment (3) provided at its upper part with a central burner (16), and featuring below the burner a tangential inlet through which hot gas is fed, via a duct (5), from the cooler (4) to the burning compartment (3), said duct (5) being provided with an inlet (14A) for raw meal, the lower part of the burning compartment (3) being provided with a connection (7) to the calciner (2), and a second connection (6) directing the exhaust gases from the kiln (1) to the calciner (2).
